Catheter-Related Arterial Thrombosis in Neonates and Children: A Systematic Review
Bibliographic record
Abstract
Catheter-related arterial thrombosis (CAT) is increasingly recognized in children. Available data are scarce and based on expert opinions. This systematic review aimed to identify knowledge on paediatric CAT. Among 3,484 publications, 22 met inclusion criteria. Fourteen reported on CAT due to umbilical arterial catheter (UAC), two to extremity indwelling catheter (EIC), one to both and five to cardiac catheter (CC). The overall cumulative incidence of CAT was 21% (95% confidence interval [CI], 13-31) with a relative incidence of 20% (95% CI, 10-33) for UAC and 11% (95% CI, 3-21) for CC-related CAT. The incidence of EIC-related CAT ranged from 3.4 to 63%. Clinical presentation of CAT included symptoms of acute limb ischaemia (79%, 95% CI, 54-97), arterial hypertension (55%, 95% CI, 23-86) and congestive heart failure (28%, 95% CI, 7-53). Underlying conditions of UAC-related CAT included prematurity (70%, 95% CI, 31-98), respiratory distress syndrome (56%, 95% CI, 46-65), asphyxia (41%, 95% CI, 15-69), infection (32%, 95% CI, 13-55), persistent ductus arteriosus (28%, 95% CI, 13-45), meconium aspiration (16%, 95% CI, 8-25) and congenital heart disease (9%, 95% CI, 2-19). Congenital heart disease was the likely condition in EIC- and CC-related CAT. Antithrombotic treatment included thrombolysis (71%, 95% CI, 47-91), heparin (70%, 95% CI, 41-94) and thrombectomy (46%, 95% CI, 10-95) alone or in combination. Complete resolution rate of CAT was 82% (95% CI, 65-96). Long-term complications included arterial hypertension (26%, 95% CI, 0-66) and limb amputation (12%, 95% CI, 1-31). The overall all-cause mortality rate was 7% (95% CI, 2-14). In conclusion, CAT occurs at an increased incidence in neonates and children and is potentially associated with poor outcome. However, limited data are available on paediatric CAT. This systematic review identifies the rationale for further studies on CAT in paediatric patients.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
